Continuous reboot on WiFi

Postby linhart » Fri May 24, 2019 5:46 am

Hello,
I use ESP32 and on one chip the program when I turn on wifi continually restarts without wifi works OK.
I've tried a stronger source for CPU, but erase Flash has not missed it?
What could it be. Also in your book I was looking for info but also samples with wifi also report this error?

That means you still have power supply issues of some kind. Try to change everything: USB cable, PC, maybe power the board from an external PSU.

Then your issue is something else and I'd suggest starting your own topic, preferably with more information than just the reset reason you get.
